问题描述:

请问.英语过去式什么时候有be 动词.was were 我搞不清哦.
I was at home yesterday.I played ping-pong last weekend.
有介词才用吗?直接连动词就不需要吗?
现在式是 I am at home today.I playing ping-pong

过去式不加Be V
你说要加Be V的是过去『进行』式
过去进行式用Be V的话后面的动词会变成V.ing
然后现在式:I am at home today.I am playing ping-pong.
(进行式一定是Be V+V.ing)
was跟were?was用在单数主词(I you he she it……)were用在复数主词.
补充:用Be V可能是进行式也可能是被动式,要注意看后面的动词是什麼唷!接V.ing就是进行式,接上过去分词(p.p)就是被动式ˇ
